[英]Intents issue in eclipse android
我有意圖的問題。 我在主要活動中使用它並調用另一個活動,但單擊它再次調用主要活動。 這是我的代碼
主要活動.java
package com.umair.facebook;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.ImageView;
import android.widget.TextView;
public class MainActivity extends Activity {
ImageView img1;
TextView txt, txt3;
Button like, share, update;
EditText et1;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
img1 = (ImageView) findViewById(R.id.img);
txt = (TextView) findViewById(R.id.name);
txt3 = (TextView) findViewById(R.id.status);
like = (Button) findViewById(R.id.Like);
share = (Button) findViewById(R.id.Share);
update = (Button) findViewById(R.id.Comment);
et1 = (EditText) findViewById(R.id.editText1);
like.setOnClickListener(new View.OnClickListener() {
@Override public void onClick(View v) {
// TODO Auto-generated method stub
like.setText("Liked");
}
});
share.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
share.setText("Shared");
}
});
update.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub startGame();
}
});
}
private void startGame() {
// TODO Auto-generated method stub
Intent lanuchGame = new Intent(MainActivity.this, Result.class);
startActivity(lanuchGame);
}
}
Result.java(第二個活動)
package com.umair.facebook;
import android.os.Bundle;
import android.widget.Button;
import android.widget.EditText;
import android.widget.ImageView;
import android.widget.TextView;
public class Result extends MainActivity {
ImageView img;
TextView txt1, txt2;
Button btn1, btn2,btn3;
EditText et;
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
setContentView(R.layout.result_1);
super.onCreate(savedInstanceState);
img =(ImageView)findViewById(R.id.img1);
txt1= (TextView)findViewById(R.id.nam);
txt2= (TextView)findViewById(R.id.stats);
btn1=(Button)findViewById(R.id.Liked);
btn2=(Button)findViewById(R.id.Shared);
et=(EditText)findViewById(R.id.editText); } }
在第二個Activity
setContentView()
super.onCreate(savedInstanceState)
之前調用super.onCreate(savedInstanceState)
。
