如何在安卓中长按侦听器上编辑贴纸视图文本

Question

我正在开发贴纸应用程序，我可以在其中向贴纸视图添加文本。我可以翻转，旋转和删除贴纸文本。现在我想在长按贴纸文本时编辑贴纸视图的文本。 这是将文本贴纸添加到屏幕的代码。

imgText.setOnClickListener(new View.OnClickListener()
{
@Override
public void onClick(View v) {
isEffectsVisible = isSttickerVisible = false;
gridView.setVisibility(View.GONE);
recycler_Effect.setVisibility(View.GONE);
recyclerView.setVisibility(View.GONE);
final Dialog dialog = new Dialog(MainActivity.this);
// Include dialog.xml file
dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
dialog.getWindow().setBackgroundDrawable(
new ColorDrawable(Color.TRANSPARENT));
dialog.setContentView(R.layout.text_custom_dialog);
dialog.setCancelable(false);
// Set dialog title
et_view = (EditText) dialog.findViewById(R.id.et_view);

// et_view.setText("" + txtHidden.getText().toString().trim());
dialog.setTitle("Text Appearance");
dialog.show();
mSpinner_text_style = (Spinner) dialog
.findViewById(R.id.spinner_text_style);
mIbtn_color_text = (ImageButton) dialog
.findViewById(R.id.ibtn_color_text);
TextAdapter adapter = new TextAdapter(MainActivity.this,
R.layout.spinner_row, style);
mSpinner_text_style.setAdapter(adapter);
mSpinner_text_style
.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
@Override
public void onItemSelected(AdapterView<?> arg0,
View arg1, int arg2, long arg3) {
// TODO Auto-generated method stub
photoEditorApplication.setPosition(arg2);
}
@Override
public void onNothingSelected(AdapterView<?> arg0) {
// TODO Auto-generated method stub
}
});
mIbtn_color_text.setBackgroundColor(photoEditorApplication.getColor());
mIbtn_color_text.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
showColorPickerDialogDemo();
}
});

Button declineButton = (Button) dialog
.findViewById(R.id.btn_cancel);
// if decline button is clicked, close the custom dialog
declineButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// Close dialog
dialog.dismiss();
}
});
Button Ok = (Button) dialog.findViewById(R.id.btn_ok);
// if decline button is clicked, close the custom dialog
Ok.setOnClickListener(new View.OnClickListener()
{
@Override
public void onClick(View v)
{
// Close dialog
txtHidden = null;
txtHidden = new TextView(MainActivity.this);
final FrameLayout.LayoutParams params =
new FrameLayout.LayoutParams(FrameLayout.LayoutParams.WRAP_CONTENT,
FrameLayout.LayoutParams.WRAP_CONTENT);
txtHidden.setLayoutParams(params);
txtHidden.setTextColor(photoEditorApplication.getColor());
Typeface face = Typeface.createFromAsset(getAssets(),
style[photoEditorApplication.getPosition()]);
txtHidden.setTypeface(face);
txtHidden.setTextSize(60);
String s = et_view.getText().toString().trim();
Log.e("et text", s);
txtHidden.setText(" " + s + " ");

if (txtHidden.getText().toString().trim().length() == 0) {
Snackbar snackbar = Snackbar.make(mRootLayout, "Please Enter Text", Snackbar.LENGTH_LONG);
snackbar.getView().setBackgroundColor(getResources().getColor(R.color.colorPrimary));
snackbar.show();
} else {

//                            
Toast.makeText(MainActivity.this,txtHidden.getText()+" 
niravvvv",Toast.LENGTH_LONG).show();
txtHidden.setVisibility(View.INVISIBLE);
txtHidden.setDrawingCacheEnabled(false);
mainFrame.addView(txtHidden);

new CountDownTimer(1000, 1000) {
@Override
public void onTick(long millisUntilFinished) {
}
@Override
public void onFinish() {
txtHidden.setDrawingCacheEnabled(true);
txtHidden.buildDrawingCache();
sticker_view.setVisibility(View.VISIBLE);
sticker_view.setWaterMark(txtHidden.getDrawingCache(), null);
dialog.dismiss();
}
}.start();
}
}
});
// ===========================================

}
});

下面有2 次点击列表者检查

t1.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
Toast.makeText(getBaseContext(), "Clicked", Toast.LENGTH_SHORT).show();
}
});
t1.setOnLongClickListener(new View.OnLongClickListener() {
@Override
public boolean onLongClick(View v) {
// TODO Auto-generated method stub
Toast.makeText(getBaseContext(), "Long Clicked", Toast.LENGTH_SHORT).show();
return true;
}
});

在 onTouch(( 方法的 Stickerview 类中，长按 case 您必须调用接口(在 StickerView 类中(方法，您必须在 Mainactivity 中安装并覆盖该接口
