我无法显示警告对话框。我把它放到了调试模式,它完成了所有事情,然后即使调试器处理该行,也不会显示菜单,然后转到下一段代码。
if(game.checkForPromotion(startRow, startCol)){
AlertDialog.Builder builder = new AlertDialog.Builder(GameActivity.this);
builder.setTitle("Pick a piece")
.setItems(R.array.pieces_array, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
// The 'which' argument contains the index position
// of the selected item
}
});
builder.create().show();
Log.d("GameActivity: ", "Is it crashing before this?");
}
Log.d("GameActivity: ", "Totally done with alert");
// More Code

我使用您的源代码运行,我将 [R.array.pieces_array] 的值更改为我的变量 [final CharSequence [] items = {“这是setItems的内容”} ] 即可。 我运行程序和警告对话框显示确定。 源代码显示对话框确定:
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
final CharSequence[] items = {"This is content of setItems"};
AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this);
builder.setTitle("Pick a piece")
.setItems(items, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
// The 'which' argument contains the index position
// of the selected item
}
});
builder.create().show();
Log.d("GameActivity: ", "Is it crashing before this?");
}
我认为您需要检查文件中的其他源代码。

试试这个,它对我有用
new AlertDialog.Builder(getContext(), android.R.style.Theme_DeviceDefault_Light_Dialog_NoActionBar_MinWidth)
.setTitle("Title")
.setMessage("My message")
.setPositiveButton("OK", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
// get ok button click
}
})
.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
// get cancel button click
dialog.dismiss();
}
})
.show();
