需求：现在自定义的view中监听物理键
结果：onKeyDown方法根本没走，无法生效。
解决方法：创建View以后AddView之前执行如下方法
if (context == null){
if (SCUtils.getTopActivityInstance() == null){
return;
}
screenCastControlView = new ScreenCastControlView(SCUtils.getTopActivityInstance());
}else {
screenCastControlView = new ScreenCastControlView(context);
}
screenCastControlView.setFocusable(true);
screenCastControlView.setFocusableInTouchMode(true);
screenCastControlView.requestFocus();
screenCastControlView.requestFocusFromTouch();
DyPluginBridgeUtils.addView(screenCastControlView);
实现自定义View
import android.content.Context;
import android.util.AttributeSet;
import android.view.KeyEvent;
import android.view.LayoutInflater;
import android.view.View;
import android.widget.LinearLayout;
import android.widget.TextView;
import tv.douyu.plugin.demo.SCApplication;
import tv.douyu.plugin.screencast.R;
public class ScreenCastControlView extends LinearLayout implements View.OnClickListener {
private Context mContext;
private TextView tv_device_name;
private TextView tv_wifi_name;
private TextView definiton_select;
private ExitDialog mExitDialog;
private SCDefinitionSelectDialog definitionSelectDialog;
public ScreenCastControlView(Context context) {
super(context);
this.mContext = context;
initView();
}
public ScreenCastControlView(Context context, AttributeSet attrs) {
super(context, attrs);
this.mContext = context;
initView();
}
public ScreenCastControlView(Context context, AttributeSet attrs, int defStyleAttr) {
super(context, attrs, defStyleAttr);
this.mContext = context;
initView();
}
private void initView() {
View view = LayoutInflater.from(SCApplication.getInstance().getApplicationContext()).inflate(R.layout.view_screen_cast_control, this);
TextView exit_cast = view.findViewById(R.id.exit_cast);
exit_cast.setOnClickListener(this);
LinearLayout ll_back = view.findViewById(R.id.ll_back);
ll_back.setOnClickListener(this);
}
@Override
public void onClick(View v) {
switch (v.getId()) {
case R.id.definiton_select:
dialogList();
break;
default:
break;
}
}
private void dialogList() {
if (definitionSelectDialog == null){
definitionSelectDialog = new SCDefinitionSelectDialog(mContext);
}
definitionSelectDialog.show();
}
@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
switch (keyCode) {
case KeyEvent.KEYCODE_VOLUME_UP:
addMediaVolume();
return true;
case KeyEvent.KEYCODE_VOLUME_DOWN:
cutMediaVolume();
return true;
default:
break;
}
return super.onKeyDown(keyCode, event);
}
