看到这个:
package us.simpleit;
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.view.ViewGroup;
import android.widget.Button;
import android.widget.EditText;
import android.widget.LinearLayout;
import android.widget.TextView;
public class SimpleGUI extends Activity {
TextView tv;
EditText et;
LinearLayout ll;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//LinearLayout ll = new LinearLayout(this);
ll = new LinearLayout(this);
ll.setOrientation(android.widget.LinearLayout.VERTICAL);
ll.setLayoutParams(new ViewGroup.LayoutParams(-1,-1));
// ARGB: Opaque Red
ll.setBackgroundColor(0x88ff0000);
tv = new TextView(this);
tv.setLayoutParams(new ViewGroup.LayoutParams(-1,-2));
tv.setText("sample text goes here");
// ARGB: Opaque Green
tv.setBackgroundColor(0x5500ff00);
ll.addView(tv);
et = new EditText(this);
et.setLayoutParams(new ViewGroup.LayoutParams(-1,-2));
et.setText("edit me please");
// ARGB: Solid Blue
et.setBackgroundColor(0xff0000ff);
ll.addView(et);
Button btn = new Button(this);
btn.setText("Go!");
btn.setOnClickListener(new Button.OnClickListener() {
public void onClick(View v) {
tv.setText(et.getText().toString());
}
});
ll.addView(btn);
setContentView(ll);
//setContentView(R.layout.main);
}
}
在这里,我采用了一个 TextView 和一个 EditText。取而代之的是,您可以采用两个 TextView 或您想要的任意数量的视图。
享受。:)
