Android 自定义AlertDialog并通过AlertDialog修改TextView的值

点击按钮“E”跳出AlertDialog进行TextView的修改：

button_edit.setOnClickListener(new View.OnClickListener() {@Overridepublic void onClick(View v) {// TODO Auto-generated method stubLayoutInflater layoutInflater = (LayoutInflater)getSystemService(Context.LAYOUT_INFLATER_SERVICE);final View view = layoutInflater.inflate(R.layout.layout_editdialog, null);AlertDialog alertDialog = new AlertDialog.Builder(CallActivity.this).setTitle(getResources().getString(R.string.dialog_title)).setView(view).setPositiveButton(getResources().getString(R.string.dialog_ok), new DialogInterface.OnClickListener() {@Overridepublic void onClick(DialogInterface dialog, int which) {// TODO Auto-generated method stubEditText mEditText = (EditText)view.findViewById(R.id.editText_editname);String newName = mEditText.getText().toString();//这里就获取到了修改到的值，剩下的就是把这个newName用TextView的setText方法放入}}).setNegativeButton(getResources().getString(R.string.dialog_cancel), new DialogInterface.OnClickListener() {@Overridepublic void onClick(DialogInterface dialog, int which) {// TODO Auto-generated method stubdialog.dismiss();}}).create();alertDialog.show();}});
