[英]How to make AlertDialog view in Input method Service?
I would like to make an input method which is used only for SoftKeyboard. 我想制作一种仅用于SoftKeyboard的输入法。 My how to make popup onkey event in input method.
我如何在输入法中制作弹出onkey事件。
I am creating Dialog but here is problem you see my logcat: 我正在创建Dialog,但是这里的问题是您看到我的logcat:
09-14 11:16:54.349: E/MessageQueue-JNI(7172): at android.inputmethodservice.KeyboardView.detectAndSendKey(KeyboardView.java:824)
Softkeyboard.java Softkeyboard.java
Here java code 这里的java代码
public void onKey(int primaryCode, int[] keyCodes) {
if (primaryCode == -2) {
// add this to your code
dialog = builder.create();
Window window = dialog.getWindow();
WindowManager.LayoutParams lp = window.getAttributes();
lp.token = mInputView.getWindowToken();
lp.type = WindowManager.LayoutParams.TYPE_APPLICATION_ATTACHED_DIALOG;
window.setAttributes(lp);
window.addFlags(WindowManager.LayoutParams.FLAG_ALT_FOCUSABLE_IM);
// end addons
builder.show();
}
Thanks for advance.. 感谢前进。
You need to have ACTION_MANAGE_OVERLAY_PERMISSION permission to open/display Alert onkey event in input method. 您需要具有ACTION_MANAGE_OVERLAY_PERMISSION权限才能在输入法中打开/显示Alert onkey事件。
Before you set your custom Keyboard Check for Overlay Permission. 在设置自定义键盘之前,请检查“覆盖权限”。
final boolean overlayEnabled = Settings.canDrawOverlays(MainActivity.this);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M && !overlayEnabled) {
openOverlaySettings();
}
@TargetApi(Build.VERSION_CODES.M)
private void openOverlaySettings() {
final Intent intent = new Intent(Settings.ACTION_MANAGE_OVERLAY_PERMISSION,
Uri.parse("package:" + getPackageName()));
try {
startActivityForResult(intent, RC_OVERLAY);
} catch (ActivityNotFoundException e) {
Log.e("MainActivity", e.getMessage());
}
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
switch (requestCode) {
case RC_OVERLAY:
final boolean overlayEnabled = Settings.canDrawOverlays(this);
if (overlayEnabled) {
preferenceManager.setBooleanPref(IS_CYBER_BULLING_ON, true);
Intent intent = new Intent(MainActivity.this, ImePreferences.class);
startActivity(intent);
overridePendingTransition(android.R.anim.fade_in, android.R.anim.fade_out);
} else {
// switchCyberBulling.setChecked(false);
}
// Do something...
break;
}
}
Then inside your SoftKeyboard.java class, put code for alert dialog & set alert type of "TYPE_APPLICATION_OVERLAY". 然后,在您的SoftKeyboard.java类中,放入警报对话框代码,并将警报类型设置为“ TYPE_APPLICATION_OVERLAY”。
AlertDialog.Builder builder = new AlertDialog.Builder(this)
//set icon
.setIcon(android.R.drawable.ic_dialog_alert)
//set title
.setTitle("Warning!")
//set message
.setMessage("This is alert dialog!")
//set positive button
.setPositiveButton("Okay", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialogInterface, int i) {
//set what would happen when positive button is clicked
dialogInterface.dismiss();
}
})
//set negative button
.setNegativeButton("Dismiss", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialogInterface, int i) {
//set what should happen when negative button is clicked
dialogInterface.dismiss();
}
});
AlertDialog alertDialog = builder.create();
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
alertDialog.getWindow().setType(WindowManager.LayoutParams.TYPE_APPLICATION_OVERLAY);
}else{
alertDialog.getWindow().setType(WindowManager.LayoutParams.TYPE_SYSTEM_ALERT);
}
alertDialog.show();
Do not forget for Draw Overlay Permission. 不要忘记“绘制叠加层权限”。 Hope this helps you.
希望这对您有所帮助。 :)
