[27.EditText soft keyboard]
EditText does not pop up the soft keyboard initially, only the cursor is displayed, click and then pop up
Solution 1:
Set in the activity property of the manifest
android:windowSoftInputMode="stateHidden"
Solution 2:
InputMethodManager inputMethodManager = (InputMethodManager)this.getSystemService(Context.INPUT_METHOD_SERVICE); inputMethodManager.hideSoftInputFromWindow(et.getWindowToken(), 0);
Solution 3:
By default, the first EditText gets the focus. The solution is to add a view that is not displayed to force the focus, such as
<View android:layout_width="0dip" android:layout_height="0dip" android:focusableInTouchMode="true" />

[soft keyboard does not block the input box]

Method 1: in your activity Medium oncreate in setContentView Write this code before getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_ADJUST_PAN); Method 2: at the beginning of the project AndroidManifest.xml Add in the corresponding interface in the file android:windowSoftInputMode="stateVisible|adjustResize" This will move the screen up as a whole. If you add android:windowSoftInputMode="adjustPan"The keyboard will cover the screen. Meaning of each value: stateUnspecified: The state of the soft keyboard is not specified. The system will select an appropriate state or theme dependent settings stateUnchanged: When this activity When it appears, the soft keyboard will remain in the previous position activity The state in the, whether hidden or displayed stateHidden: User selection activity When, the soft keyboard is always hidden stateAlwaysHidden: When Activity When the main window gets the focus, the soft keyboard is always hidden stateVisible: Soft keyboards are usually visible stateAlwaysVisible: User selection activity When, the soft keyboard always displays the status adjustUnspecified: The default setting, which is usually hidden or displayed at the discretion of the system adjustResize: Should Activity Always resize the screen to make room for the soft keyboard adjustPan: The content of the current window will automatically move so that the current focus is never covered by the keyboard and the user can always see the part of the input content Method 3:(Use here) Put the top layout replace with ScrollView，Or at the top Layout Add another layer on top ScrollView. This will scroll the soft keyboard with the input box, and the soft keyboard will always be at the bottom. General top View Need to add android: fitsSystemWindows="true"
[28. Timer] (note that it is not a delayer)
1. postDelayed method of handler class:
Handler mHandler = new Handler();
Runnable r = new Runnable() {
@Override
public void run() {
//do something
//Execute the run method every 1s
mHandler.postDelayed(this, 1000);
}
};
Call in main thread: mHandler.postDelayed(r, 100);//100 ms delay
2. Use the handler+timer+timeTask method:
Handler handler = new Handler() {
@Override
public void handleMessage(Message msg) {
if (msg.what == 1){
//do something
}
super.handleMessage(msg);
}
};
Timer timer = new Timer();
TimerTask timerTask = new TimerTask() {
@Override
public void run() {
Message message = new Message();
message.what = 1;
handler.sendMessage(message);
}
};
Call in main thread: timer.schedule(timerTask,1000,500);//The run method is executed every 500 milliseconds with a delay of 1 s
3.Thread+handler method:
Handler handler = new Handler() {
@Override
public void handleMessage(Message msg) {
if (msg.what == 1){
//do something
}
super.handleMessage(msg);
}
};
class MyThread extends Thread {//The Runnable interface can also be used here
@Override
public void run() {
while (true){
try {
Thread.sleep(1000);//Every 1s
Message msg = new Message();
msg.what = 1;
handler.sendMessage(msg);
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}
}
Call in main thread: new Thread(new MyThread()).start();

2.timer + TimerTask method:
Timer timer = new Timer();

https://blog.csdn.net/chenbaige/article/details/77991594
Get the size (width and height) of the View in the activity. If you only write getWidth() and getHeight(), you can't get the width and height of the View
Question answer: in fact, the measure process of View and the life cycle method of Activity are not executed synchronously. Therefore, it is impossible to ensure that the View has been measured when the Activity completes executing a life cycle method. In this case, the obtained size is 0.
//1. Get the following from the onWindowFocusChanged method of the activity:
//When the onWindowFocusChanged method is executed, it means that the View has been initialized, the width and height have been measured and finally confirmed,
//onWindowFocusChanged will be executed multiple times and will be called once when the Activity gets focus and loses focus.
// That is, the onPause and onResume methods are called repeatedly when they are executed.
@Override
public void onWindowFocusChanged(boolean hasFocus) {
super.onWindowFocusChanged(hasFocus);
if (hasFocus) {
int width = bbb.getMeasuredWidth();
int height = bbb.getMeasuredHeight();
ZLog.e("1.view Width:" + width + " view Height:" + height);
}
}
//2.View.post method
//When the runable method is executed, all initialization measurement method descriptions of View have been executed.
view.post(new Runnable() {
@Override
public void run() {
int width = bbb.getMeasuredWidth();
int height = bbb.getMeasuredHeight();
ZLog.e("2.view Width:" + width + " view Height:" + height);
}
});
//3.ViewTreeObserver
//When the state of the View tree changes or the visibility of the View inside the View tree changes, onGlobalLayout will be called back.
//Note: onGlobalLayout will be called multiple times as the state of the View tree changes.
ViewTreeObserver observer = view.getViewTreeObserver();
observer.addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
@Override
public void onGlobalLayout() {
view.getViewTreeObserver().removeOnGlobalLayoutListener(this);
int width = view.getMeasuredWidth();
int height = view.getMeasuredHeight();
ZLog.e("3.view Width:" + width + " view Height:" + height);
aaa.setMaxWidth(widthP - width - 10);//I'm late. aaa has exceeded this time. width=0
}
});
//4.measure
//After manually calling measure, the View will call the onMeasure method to initiate measurement on the View. After measurement, you can obtain the measured width and height.
//However, specific parameter values can only be obtained by processing the LayoutParams parameters according to different situations:
//4.1) the LayoutParams parameter of view is match_parent:
//In this case, the specific width and height value cannot be obtained, because when the measurement mode of View is match_ When parent, the width and height value takes the remaining space of the parent container as its own width and height.
//At this time, the size of the parent container cannot be obtained, so the acquisition will fail.
//4.2) the LayoutParams parameter of view is the specific value: (0?)
int widthV = View.MeasureSpec.makeMeasureSpec(0, View.MeasureSpec.EXACTLY);
int heigtV = View.MeasureSpec.makeMeasureSpec(0, View.MeasureSpec.EXACTLY);
bbb.measure(widthV, heigtV);
int width1 = bbb.getMeasuredWidth();
int height1 = bbb.getMeasuredHeight();

//4.3) wrap_content: Yes

int height22 = View.MeasureSpec.makeMeasureSpec((1 << 30) - 1, View.MeasureSpec.AT_MOST);

int height222 = bbb.getMeasuredHeight();
int width222 = bbb.getMeasuredWidth();
ZLog.e("5.view Width:" + width222 + " view Height:" + height222);
//aaa.setMaxWidth(widthP - width222 - 10);
[I use this]
//(can be used) Note: View.MeasureSpec.UNSPECIFIED
//4.1 when the TextView attribute is wrap_ How to obtain the width of content, especially when the interface is not displayed, such as in RecycleView
