Android DialogFragment（2）
附录文章1简单介绍了如何实现一个DialogFragment，本文再介绍一种简单的方法：直接重写DialogFragment的onCreateDialog返回一个AlertDialog实现对话框。本文的例子和附录文章1不同的地方：不在依赖onCreateView。
代码运行逻辑简述：功能简单，当点击FloatingActionButton
后弹出一个自定义的DialogFragment，该DialogFragment重写了onCreateDialog，返回一个自定义的AlertDialog。
package zhangphil.app;
import android.app.AlertDialog;
import android.app.Dialog;
import android.app.DialogFragment;
import android.content.DialogInterface;
import android.os.Bundle;
import android.support.design.widget.FloatingActionButton;
import android.support.v7.app.AppCompatActivity;
import android.support.v7.widget.Toolbar;
import android.view.LayoutInflater;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.widget.TextView;
public class MainActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab);
fab.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
MyDialogFragment dialog = new MyDialogFragment();
dialog.show(getFragmentManager(), "zhangphil");
}
});
}
public static class MyDialogFragment extends DialogFragment {
@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
LayoutInflater inflater = getActivity().getLayoutInflater();
View view = inflater.inflate(android.R.layout.simple_list_item_1, null);
TextView text = (TextView) view.findViewById(android.R.id.text1);
text.setText("zhang phil @ csdn");
builder.setView(view)
.setPositiveButton("确定",
new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int id) {
}
}).setNegativeButton("取消", null);
return builder.create();
}
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_main, menu);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
//noinspection SimplifiableIfStatement
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
}
代码运行结果如图：
