AlertDialog 基本使用

1,设置dialog 背景

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle"
    >
    <corners android:radius="5dp"></corners>
    <solid android:color="@android:color/white"/>

</shape>

2,android codee

public class DialogActivity extends AppCompatActivity {

    @Bind(R.id.button2)
    Button button2;
    AlertDialog dialog;
    AlertDialog.Builder builder;
    View view;


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_dialog);
        ButterKnife.bind(this);
        view = LayoutInflater.from(this).inflate(R.layout.dialog_layout, null);

        dialog = new AlertDialog.Builder(this).create();
        //点击其他的地方关闭dialog
        dialog.setCanceledOnTouchOutside(true);
        
        view.findViewById(R.id.cnacel).setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                dialog.dismiss();
            }
        });
        view.findViewById(R.id.sure).setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                dialog.dismiss();
            }
        });
    }

    @OnClick(R.id.button2)
    void show() {
        dialog.show();
        dialog.getWindow().setContentView(view);
    }

}
