問題： - startActivity（）被android 調用system_process無限次。所以下面的代碼打開MainActivity但隨後MainActivity被凍結/掛起，幾分鐘後android關閉。startActivity（）被android系統進程無限次調用
我有兩個活動：
- RegisterActivity
- MainActivity
registeration過程完成後，我想將用戶重定向到主屏幕（ieMainActivity），所以我用這個代碼開始活動： -
Button btnSubmit = (Button) findViewById(R.id.btnSubmit);
btnSubmit.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
Intent intent = new Intent(RegisterActivity.this,MainActivity.class);
startActivity(intent);
}
});
但是startActivit y（）被android系統稱爲無限次。我通過Logcat發現了這一點。該logcat的輸出是： -

MainActivity代碼：
public class MainActivity extends Activity {
AlertDialog.Builder builder;
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
builder = new AlertDialog.Builder(this);
Button btnEnter = (Button) findViewById(R.id.btnEnter);
btnEnter.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
if (RegisterActivity.loggedIn) {
startActivity(new Intent(MainActivity.this,
AddActivity.class));
} else {
Utility.showAlertDialog(builder, "Please Log In!");
}
}
Button btnSettings = (Button) findViewById(R.id.btnSettings);
btnSettings.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
startActivity(new Intent(MainActivity.this,
RegisterActivity.class));
}
});
}
RegisterActivity代碼：
public class RegisterActivity extends Activity {
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.register);
builder = new AlertDialog.Builder(this);
etName = (TextView) findViewById(R.id.etName);
etEmail = (TextView) findViewById(R.id.etEmail);
Button btnSubmit = (Button) findViewById(R.id.btnSubmit);
btnsubmit.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
Intent intent = new Intent(RegisterActivity.this,
MainActivity.class);
startActivity(intent);
}
});
}
}
這logcat的輸出是連續的，直到我關閉模擬器如果我不關閉！模擬器然後android自動重啓。只是系統掛起導致它無限地調用startActivity（）！
發佈更多代碼。我猜你在調用performClick循環或其他東西。或者它在您的HomeActivity – njzk2 2013-03-20 10:44:20
