Reasons and solutions why Android WebView cannot pop up the soft keyboard

requestFoucs(); is invalid.

requestFoucsFromTouch(); is invalid.

webview.setTouchListener; Invalid.

The problem:

When inheriting WebView, pay attention to the construction method:

public CommonWebView(Context context) {
super(context);
init();
}
public CommonWebView(Context context, AttributeSet attrs) {
super(context, attrs);
init();
}
public CommonWebView(Context context, AttributeSet attrs, int defStyleAttr) {
super(context, attrs, defStyleAttr);
init();
}

##defStyleAttr cannot pass 0, the following is the wrong way to write it ：

public CommonWebView(Context context) {
this(context,null,0);
}
public CommonWebView(Context context, AttributeSet attrs) {
this(context, attrs,0);
}
public CommonWebView(Context context, AttributeSet attrs, int defStyleAttr) {
super(context, attrs, defStyleAttr);
init();
}

The above is the reason why Android WebView cannot pop up the soft keyboard and the solution introduced by the editor. I hope it will be helpful to everyone.
